IMPROVEMENT IN FANNlNG-MIKLLS.

The Schedule referred to in these Letters 'Patent and making part of the sence.

"To all-whom 'it may concern:

Be it known that Ive-FRANK SAUnngand JOHN` CoERvEr., of Waterloo, in the county of Monroe and. State of Illinois, have invented a 'new and improi'ed Fanning-Mill; and we do hereby declare that the fol# -lowing is a full, clear, and 'exact description thereof, f

which will enable others skilled in the art to make and' vuse the saine, reference being had to the accompanying drawing forming part of this specification.

'lfhis invention relates to improvements in fanningmills, and consists inY the ,improved combination and arrangement of the several parts, all 'as hereinafter described.

Figure l is a side elevation of our improved fauningmill, a part being broken out to show the arrangement of the sieves. ,A

Figure 2'is a transverse section taken on the line xxoffgl.'

Figure 3 is a plan view of the same.

`Similar letters of referenceiudicate corresponding parts.

The frame or case A, the fan B, and the yhopper are arranged substantially the same as inhother machines.

The fan-shaft is driven by a small pulley, D, worked by a band, E, and large driver, F, the latter mounted Ona stud-pin projecting from the side 'of the case,- near the end where the sieves are suspended.

The sieve-frame is suspende'dby four hangers, G,

of the case,so that the said. sieve-frame may moveto and from the lan-shaft in shaking.'

The shaking motion is imparted by two connectingrods, I, one ou each side, attached to cranks Kon the fan-shaft, and to studfpins L projecting through the fanuing-mill case;

' M is a kcouveyeror screen arranged in a trough underthe'lower-ends of `the screens, so as to receive the grain and convey it out at the spoutN, on one side.

' Thisconveyer is worked by a belt, P, from a pulley on theffan-shaft, as clearly shown in figs. 1 and 3.

It' will be seen that, by the employment of the two cranks and connecting-rods for workingthe screencase, the friction and wear of -the connections are so 'divided up that the effect is much less injurious than when only onel crank and connecting-rod is used.

Moreover, the strain being expended alike on both `sides of the case, is less iujurious,'andthe machine4 will'staud more steady on the'i'loor.

Another advantage of this arrangement is that the screen-case, being so arranged as not to strike lagainst the sides of' the fan, runs much smoother, andwith less noise than when arranged in the common way.

The employment of the conveyer in the manner described is a great convenience-for delivering the grain into lsacks or any other receptacle.

Having thus described our invention, Y fe claim as new and desire to secure by Letters Patent- Qlhe'fan B, shat'tO, driver F, pulleys D, cranks R, hangers G; connecting-rods I,'belts E and P, and conveyerV M, when said parts are constructed, combined,

and arranged for operation substantially as and for the purpose described.
